Abstract
A cross flow membrane system for separating feed water into a concentrate stream and a permeate stream which includes a cross-flow membrane module, a pump for pressurizing feed water for supply to the module and a flow control manifold block having a permeate, a concentrate bore and a concentrate orifice for controlling the flow of concentrate from the system and the operating pressure within the cross-flow membrane module. The manifold block simplifies the manufacture, operation and maintenance of the system and allows elimination of many of the tubes, hoses and valves which are commonly required in prior art systems.
